To all whom it may concern:

Be it known that 1, JOHN Korma, a citizen of the United States, residing at Atlanta, in

the county of Fulton and State of Georgia,

have invented a new and useful improve;

ment in Machines for Manufacturing One- Piece Folded Sheet-Metal Tu entine-Cups, of which the. following is a specification.

M invention relates to improvements in mac'iines for manufacturing long, narrow,-

deep, one

piece folded sheet metal turpentine cups,

aving substantially upright but slightly flaring sides and widely flaring ends and slightly flaring or incline .side die memberd or faces and with .a pair of opposing. widely flaring or inclined end die members or faces witlran angular open spa'ce at the cor,- ners between the side and end die members or faces and a (:06 crating male forming diehavingcorrespo'n ing slightly flarin or inclined side die faces or members anfwidely I flaring or inclined end diefaees or members,

the s de die members being provided with rejecting wingsat each end, said wings hav- 1n inclined lower edges.

fin the drawing, Fi ure 1 is a front elevation of a machine em odying my invention. Fi%; 2 is a detail vertical section on line 2 2' of ig. 1. Fig. 3 is a detail bottom view of the male forming die. tion on line 4- 4 of Fi 3. Fig. 5 is a detail lan view of the female forming die. Fi 6 1s a cross section on line 6-6 of Fig. 5. i ig. 7 is a detail side elevation looking from line 7-7 of Fig. 5. Fig. 8 is a perspective view ofthe sheet metal blank as formed by the machine and Fig. 9 is a similar view of the long, narrow, deep one iece folded sheet metal turpentine cup, in t 1e manufacture of which the machine involving my invention Fig. 4 is a cross secis used.

. The frame A, bad plate B and cross head or slide C may all be of an suitable con struction. The slide trave s in suitable guides or ways A on the frame of the ma chine andis reciprocated up and down as required by a crank g on the driving shaft G through 31 suitable pitman oifiinnccting link g.

The male forming die D is frther pro I vided with slightly flaring or inclined side die faces or members 11? d which are preferably formed, in separate pieces from the-(lie l) of hardened steel, and rigidly and firmly but removably secured thereto bv screws (1. The bottom face d of the male forming die is preferably formed on the lower edges of the side die members (i Each of the side die members if is provided at each end "with an integral wing d projecting beyond 'the widely flanng end die faces (1 and having their lower edges d --:irielin ed at a materially greater angle than that of the widely flaring end die The widely flaring end die faces (1 are preferably inpart formed on the side die members (i at the ends thereof will be readilyunderstoodfrornFi .3ofthedrawing The female forminbe tom'die l .4353 or menib 1", a pair of widely flaring end die faces o! nnunbersf mid a air of sli gfhtly flaring side die faces or menu )ers f the end and side dien embersj having angular openings or free 'es f between them to. accommodate the surplus stock, which forms the win s or angle folds x of the cup or vessel 1e wings d onthe side die members (1 of the male forming die'D cause the surplus stock at each corner to shape itself into wings or angle folds of true, regular and proper shape, notwithstanding the wide difierencein the flare of the ends :1 and sides as of the vessel X, and of the coijpcrating die faces or members at the sides and ends of the male and female forming dies.

The end and "side die faces or members 1 f 2 of the female forming die F- are preferab y in. separate pieces and secured by screws f to the body plate F of the female die. The bottom die face or memberf of the forming die is preferably in a separate piece from the die plate F to which the end and side die members; j P are secured at their lower edges, and it' made movable in respect to the other (lie '|n(?=1nl,;-( rs of the female forming die and furnished with guide stems f and wi th a spring f surrounding a stem f 7 so that this bottom die member f may also serve as an ejector.
